All patients with reticular erythematous mucinosis (REM) published until August 1987 are analysed. REM and plaque-like form of cutaneous mucinosis are different diseases but belong to one spectrum. REM should not be called a syndrome, because a syndrome consists of several signs mostly in various organs. REM and plaque-like form of cutaneous mucinosis are classified as mid-line mucinosis, as suggested by Steigleder and Küchmeister (8). Increasing numbers of mid-line mucinoses are published over the years, apparently midline-mucinosis are not so rare as thought before.
